Frequently Asked Questions
•What are the typical DC output voltages on the power supply board, and where can I find them?
Typically, you should find 5V DC and 12V DC outputs. The voltages are usually labeled near the connector on the power supply board itself or indicated on the wiring diagram, often affixed to the cooktop chassis.
•How do I safely remove the glass top of the cooktop without damaging it?
Consult the service manual for your specific model. Generally, you'll need to remove screws around the perimeter and carefully lift the glass, being mindful of any adhesive or clips. Use a putty knife to gently separate the glass if needed.
•If the power supply board tests good, is there a way to test the display panel directly before replacing the main control board?
Testing the display panel directly requires specialized tools and knowledge, as it communicates with the MCU via a serial data connection. Without proper equipment, it's difficult to diagnose the display panel itself. The MCU is typically the next most likely suspect if the power supply is functioning correctly.
